It is a marvel that never loses its surprise by repetition, this
aiming a ship at a mark three thousand miles away and hitting the
bull's-eye in a fog—as we did. When the fog fell on us the captain
said we ought to be at such and such a spot (it had been eighteen
hours since an observation was had), with the Scilly islands bearing
so and so, and about so many miles away. Hove the lead and got
forty-eight fathoms; looked on the chart, and sure enough this depth
of water showed that we were right where the captain said we were.
Another idea. For ages man probably did not know why God carpeted
the ocean bottom with sand in one place, shells in another, and so
on. But we see now; the kind of bottom the lead brings up shows
where a ship is when the soundings don't, and also it confirms the
soundings.

They reached Hamburg after two weeks' stormy sailing. They rested a few days there, then went to Hanover and Frankfort, arriving at Heidelberg early in May.

They had no lodgings selected in Heidelberg, and leaving the others at an inn, Clemens set out immediately to find apartments. Chance or direction, or both, led him to the beautiful Schloss Hotel, on a hill overlooking the city, and as fair a view as one may find in all Germany. He did not go back after his party. He sent a message telling them to take carriage and drive at once to the Schloss, then he sat down to enjoy the view.

Coming up the hill they saw him standing on the veranda, waving his hat in welcome. He led them to their rooms—spacious apartments—and pointed to the view. They were looking down on beautiful Heidelberg Castle, densely wooded hills, the far-flowing Neckar, and the haze-empurpled valley of the Rhine. By and by, pointing to a small cottage on the hilltop, he said:

“I have been picking out my little house to work in; there it is over there; the one with the gable in the roof. Mine is the middle room on the third floor.”

Mrs. Clemens thought the occupants of the house might be surprised if he should suddenly knock and tell them he had come to take possession of his room. Nevertheless, they often looked over in that direction and referred to it as his office. They amused themselves by watching his “people” and trying to make out what they were like. One day he went over there, and sure enough there was a sign out, “Moblirte Wohnung zu Vermiethen.” A day or two later he was established in the very room he had selected, it being the only room but one vacant.

In A Tramp Abroad Mark Twain tells of the beauty of their Heidelberg environment. To Howells he wrote:

Our bedroom has two great glass bird-cages (inclosed balconies), one
looking toward the Rhine Valley and sunset, the other looking up the
Neckar cul-de-sac, and naturally we spend nearly all our time in
these. We have tables and chairs in them; we do our reading,
writing, studying, smoking, and suppering in them.... It
must have been a noble genius who devised this hotel. Lord, how
blessed is the repose, the tranquillity of this place! Only two
sounds: the happy clamor of the birds in the groves and the muffled
music of the Neckar tumbling over the opposing dikes. It is no
hardship to lie awake awhile nights, for this subdued roar has
exactly the sound of a steady rain beating upon a roof. It is so
healing to the spirit; and it bears up the thread of one's
imaginings as the accompaniment bears up a song....
I have waited for a “call” to go to work—I knew it would come.
Well, it began to come a week ago; my note-book comes out more and
more frequently every day since; three days ago I concluded to move
my manuscripts over to my den. Now the call is loud and decided at
last. So to-morrow I shall begin regular, steady work, and stick to
it till the middle of July or August 1st, when I look for Twichell;
we will then walk about Germany two or three weeks, and then I'll go
to work again (perhaps in Munich).

The walking tour with Twichell had been contemplated in the scheme for gathering book material, but the plan for it had not been completed when he left Hartford. Now he was anxious that they should start as soon as possible. Twichell, receiving the news in Hartford, wrote that it was a great day for him: that his third son had been happily born early that morning, and now the arrival of this glorious gift of a tramp through Germany and Switzerland completed his blessings.

I am almost too joyful for pleasure [he wrote]. I labor with my
felicities. How I shall get to sleep to-night I don't know, though
I have had a good start, in not having slept much last night. Oh,
my! do you realize, Mark, what a symposium it is to be? I do. To
begin with, I am thoroughly tired and the rest will be worth
everything. To walk with you and talk with you for weeks together
—why, it's my dream of luxury. Harmony, who at sunrise this morning
deemed herself the happiest woman on the Continent when I read your
letter to her, widened her smile perceptibly, and revived another
degree of strength in a minute. She refused to consider her being
left alone; but: only the great chance opened to me.
SHOES—Mark, remember that ever so much of our pleasure depends upon
your shoes. Don't fail to have adequate preparation made in that
department.
